Computational illumination for high-throughput intensity diffraction tomography of dynamic biological samples (Conference Presentation)

Paper Abstract

We present two computational illumination strategies for high-speed Intensity Diffraction Tomography (IDT) on dynamic, unlabeled biological samples. IDT provides quantitative volumetric reconstructions of biological samples but is slow, requiring hundreds of images under diverse illumination. We developed multiplexed IDT (mIDT) and annular IDT (aIDT) as software-based and hardware-based solutions improving IDT’s acquisition speed. mIDT optimally combines illuminations into each image for faster acquisition while aIDT uses fewer, single illuminations from a ring-geometry LED grid to achieve hardware-limited 5Hz and 10Hz volume rates, respectively. We demonstrate the improvement these techniques provide on living epithelial buccal cells and Caenorhabditis elegans worms.
